PAPER-BOX VIACHIN E.

SPECIFICATION forming part of Letters Patent No. 644,569, dated March 6, 1900.

Application tiled March 29, 1899.

To v/ZZ whom it may concer-n,.-

Be it known that I, CHARLES BECK, of Phil adelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Paper-Box Machines; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains` to make and use the same, reference being had to the accompanying drawings, and to the numerals of reference marked thereon, which form part of this specification, in which- Figure 1 is a perspective view of the machine. Fig. 2 is a view in elevation of the right-hand side thereof. Fig. 3 is a top plan view. Fig. 4.- is front end elevation. Fig. 5 is a fragmentary detail view illustrating in top plan the fixed or lower cut-off knife, the adjusting means being shown in dotted lines. Fig. 6 is a fragmentary detail view, in front elevation, of both fixed or` lower and movable or upper cut-off knives. Fig. 7 is a fragmentary detail View, in end elevation, of the cut` off knives. Fig. 8 is a fragmentary detail viewshowing in end elevation the box-support spindle and the outer end of the pivoted arm in which it is carried. Fig. 9 is a fragmentary detail view showing the same parts in rear elevation. Fig. 10 is a detail sectional view of the means for securing the box-support swinging arm.

Like numerals of reference mark the same parts in all of the figures of the drawings.

This invention relates generally to machines for covering paper boxes, and more particularly to that class of such machines known to the trade as single-strip machines from the fact that the -machine uses but a single strip of paper in contradistinction to the machines which use two strips and are known as double-strip machines, although some of the improvements detailed herein are applied to both styles of machines.

The object of the present invention is to generally improve the construction and operation of these machines, increase their capacity, and simplify the form and adjustability of the various parts, such general object being carried out by providing special improvements in means for adapting the machine to expose longer portions of the glue-coated pa- Serial Noi 710,968. (No model.)

per to the action of the atmosphere for the purpose of tempering, improvements in the means for controlling the strip during teinpering, improvements in the cut-off knives, and improvements in the boxsupport spindle and its supporting pivotal arm.

With these general and special objects in view my invention consists in the improved construction, arrangement, and combination of parts hereinafter fully described and afterward specically pointed out in the ap-A pended claims.

Referring now to the drawings by numerals, the frame of the machine, which is generally made of cast metal, is composed of legs 10 11 12 13, connected by upper and lower longitudinal sections or beams 14 15 16 17 and the usual cross bars or beams 1S. Lugs 19 and 2O are formed on` the top of each of the upper longitudinal beams 14 and 15, the lugs on each beam being provided with horizontal bores or openings in line with each other to receive alongitudinal cylindrical bar, as at 21 and 22, the bar 21 lying above and parallel with the beam 14C and the bar 22 in a like re= lation to the beam 15. These bars 21 and 22 are longitudinally slidable in their supporting-lugs and may be retained in any position to which they may be adjusted by means of.

hooks 26, in which may be mounted at varif ous heights the journals of the roll 27, upon which the paper strip in the form of a roll is slipped, the wheels 2S being provided for at the ends of the roll for guiding the paper.

Holding-plates 29 are mounted on vertical pins 30, rising from blocks 31, slidablymounted on rods 21 and 22, and a bail 32 projects from one of the plates in the line of nuove-v ment of the paper strip.

33 indicates a glue box or reservoir provided with side lugs 34,' adapted to rest on bars 2 1 and 22, whereby the reservoir is supported upon said bars, the reservoir being of ordinary construction and provided with any suit; able means for heating its contents.

35 indicates the glueroller,of any ordinary IOO construction, provided with pawl-and-ratchet devices 3G to prevent backward movement. This roller is journaled in bearings in the upper edges of the sides of the glue-reservoir, as is also a shaft or bar 37, carrying a cleaner or scraper bail 3S and securable at any adjustment by a set-screw 39.

40 41 indicate the two side bars of a yoke formed of these bars, a connecting counterbalancing cross-bar 42 at one end, and a roller 43, pivoted between pins 44, at the opposite ends. A frame 45 for holding a drip-box 46 is pivoted on journal-pins44,sufiiciently loose to always hang in a line vertically below the roller 43.

47 47 are nprights secured to beams 14 and 15, between which is pivoted a frictionroller 4S.

49 indicates a cross-bar secu red between the side frames, to which is adjustably secured the lower eut-off" knife 50, said knife being backed by a bed-piece 51 between it and the cross-bar 49. Set-screws 52, passed through plain openings in bar 49 and threaded into bed-piece 51, serve to draw the bed-piece tightly against the bar 49 or against the ends of set-screws 53, threaded through said bar. The set-screws 53 are for the purpose of setting the bed-piece 51 away from bar 49.

54 indicates the movable knife, formed, as shown in Fig. 6, to give a shear cut, being lowerat one end than at the other. This knife is secured to a cross-bar 55, depending from the outer ends of two arms 5G, securedv to a shaft 57, journaled in the side beams 14 and 15 and provided at one end with a crank-arm 58, normally held down by a spring 59, connecting it with the frame, and at the other end with a similar crank-arm 60, projecting oppositely to crank-arm 5S and connected by a rod 61 to a treadle G2, pivoted to the frame.

63 indicates a circular boss formed on the outside of leg 11, from which projects a stubshaft 64, screw-threaded for a portion of its length. On this stub-shaft is mounted a circular block 65, the fit of which against the boss is improved by hollowing out the outer surface of the boss and the inner surface of the block, as shown at (56 in Fig. 10. The block G5 is diametrically grooved in its outer face to receive an arm 67, through a longitudinal slot 68 in which the stub-shaft passes. A washer 69 is mounted on the stub-shaft outside of the arm 67, and by means of a handled nut 70 the block, arm, and washer may be locked in any position.

On the outer end of the arm 67 is formeda head or boss 7l, bored horizontally to receive a spindle 72, which carries the usual box or lid support 73. A cam-shaped recess 74 is formed in the wall of the hollow in which the spindle is mounted, in which is placed a roller 75, held in position by a spring 76, which is adjustably held by a screw 77, said arrangement permitting of the free rotation of the spindle in one direction, but locking it against turning in the opposite direction. The arm G7 is also provided with a smaller bore parallel with that in which the spindle is mounted, in which is slidably mounted a rod 77, carrying at its inner end a bifurcated head 78, whose jaws straddle the spindle, fitting in a circumferential groove 79 therein. A setscrew 8O secures the rod 77 against either rotary or longitudinal movement, which by virtue of the engagement of the bifurcated head in the groove in the spindle permits of the free rotation of the spindle, but prevents longitudinal movement thereof.

8l indicates the box in one of the positions it assumes during the act of covering it with the strip 82 of paper.

The operation of my invention will be readily understood from lthe foregoing. The strip S2 passes between the holding-plates 29, under the bail 32, over the glue-roller 35, under the shaft 37, over the bail 38 to spread the glue and scrape off the surplus thereof, over the roller 43 of the yoke 4041, down and under the roller 4S, between the knives, and to the box 8l, held against the support 73. The manipulation of the box by the operator draws the strip through the described course as the box is turned, and at the proper time the strip is severed by the knives, actuated by the treadle G2.

As before mentioned, the bars 2l and 22 are longitudinally adjustable in their lugs, so that they may be projected to the rear of the machine, and the reservoir supported thereon outside of the frame to increase the length of glued strip for more thoroughly tempering it.

The tension-yoke 40 4l being pivoted to the frame, it can be readily adjusted to raise or lower the supporting-roller carried thereby, the counterbalancing of the yoke facilitating its adjustment. Its skeleton form permits of the passage of the strip of paper through the yoke below the roller 43 when desired.

By means of the connection of the movable knife 54 to the overhanging cross-bar 55 the blade is given a substantially-vertical movement, and its arrangement to give a shear cut makes the operation of cutting easier and cleaner. The adjustment of the fixed knife insures the perfect cooperation of the two knives at all times.

The pivoting of the slotted spindle-arm 67 on the stub-shaft 64 and in the diametri@ groove in the swiveled block 65 renders it easily possible to adj ust the box-supporting spindle to any desired point within the swing of the arm.

The free forward turning lateral adjustment and non-backward moving of the boxsupport have been before explained.

While I have illustrated and described what 1 consider efficient means for carrying out my invention, I do not wish to be understood as limiting myself to the exact forms and arrangements shown, but hold that any slight changes thereinfsuch as might suggest IOO IIO

themselves to the ordinary mechanic, would be clearly included within the limit and scope of my invention.

Having thus fullydescribed my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is-

1. The combination in a box-covering machine of the frame, the parallel rods adjustable longitudinally thereon to beyond the end of the frame, the paper-roll-carrying brackets removablysecured thereon at theirouter ends,

the glue-reservoir resting loosely on the top of said rods, the cut-olf knives, and the stripextending counterbalanced yoke pivotally secured to the frame between the glue-roll and the knives substantially as described.

2. The combination in a box-covering machine, of the frame, the parallel rods adjustable longitudinally thereon tobeyond the end of the frame, the paper-roll-carrying brackets removably secured thereon at theirouter ends, the glue-reservoir resting loosely on the top of the rods, the cut-off knives, and the stripextending counterbalanced yoke between the glue-reservoir and knives, substantially as described.

3. The combination in a box-covering machine of the frame, the glue-reservoir and roller mounted thereon, the cut-o knives, and the counterbalanced tension-roll-carrying yoke freely pivoted to the frame intermediate the glue-roll and knives, substantially as described.

4. The combination in a box-covering machine of the frame, a yoke pivoted thereto and counterbalanced by weights below its pivot, a tension-roll pivoted in the upper ends of the yoke, and a drip-pan suspended below the roll, substantially as described.

5. The combination in a box-covering machine of the frame, and the counterbalancing tension-roll-carrying yoke pivoted thereto, said yoke comprising two arms pivoted to the inside of the side frames whereby the body of the yoke is open to permit of the passage of the strip of paper therethrough under the roll, substantially as described.

6. The combination in a box-covering ma chine of the frame, the slotted pivoted arm thereon, the horizontally-adjustable rotary shaft mounted in the end thereof, means for locking it against backward rotation, and the boxsupport secured to the shaft, substantially as described.

7. The combination in a box-covering machine of the slotted pivoted arm, the horizon- -tal rotary shaft therein, means for locking it against backward rotation, the box-support on the shaft, the rod mounted in the arm parallel with the shaft, and the bifurcated head on the rod straddlin g the shaft in a peripheral groove therein, substantially as described.

In testimony that I claim the foregoing as my own I affix my signature in presence of two Witnesses.

CHARLES BECK.
